Burr hole craniostomy with novel use of subdural drain for evacuation of chronic subdural hematoma: Case series, literature review, and technical note

Background: Controversy continues to exist regarding optimal management of chronic subdural hematoma. We present a different way of using a subdural drain during the post-operative period to assist with drainage. Method: We present a case series of five consecutive patients who underwent subdural hematoma drainage utilizing this technique. Results: Post-operative films revealed good hematoma evacuation, minimal subdural pneumocephalus, and good brain re-expansion. Conclusion: Intraoperative subdural drain irrigation and post-operative distal drain flushing may have beneficial effects on hematoma drainage. Further testing is needed to make definitive conclusions.
